SPECIFICATION forming part of Letters Patent No. 791,632, dated June 6,1905.

Applioationiled May 31, 1904. Serial No. 210,557.

To @ZZ whom it may concern,.-

Be it known that I, WILLIE O. LINDGREN, a citizen of the United States,residing at Litchville, in the county of Barnes and State of NorthDakota, have invented certain new and useful Improvements in Ohurns, of.which the following isa specification.

This invention relates to churns; and among the objects in view is toprovide a churn which shall be comparatively simple and inexpensive inits general construction.

A further object is to provide an improved construction of churn-bodyand dasher by which butter may be quickly produced, and with thedescribed objects in view.

Theinvention consists in the novel construction, arrangement, andcombination of parts,

as hereinafter fully described.illustrated in the drawings, and pointedout in the appended claims.

In the drawings, Figure 1 is an elevation of a churn embodying theinvention. side elevation of the churn. Fig. 3 is an elevation ofthedasher detached. Fig. 4 is a plan view of the churn-body. Fig. 5 is avertical sectional view of the churn-body.

1 indicates a suitable supporting-framework adapted to support theoperative parts of the churn. Y

2 indicates the churn-body, which, as shown, is of trunco-conical shape,though it may have a cylindrical shape. The body is provided withtrunnions 3, which are removably seated in open bearings 4, secured tothe uprights of the framework, whereby the body may be tilted for thepurpose of enabling the `dasher and contents to be readily removed andalso to enable the body to be lifted from its bear-' desired purpose. I

For maintaining the churn-body in proper position during the churningoperation I proings and removed from the framework for any -vide a bentmetallic strip, plate, or lug 6, se-

Fig.2 is a ribs 10 of triangular shape in cross-section. These ribs areadapted to coperate with the' arms or bladesA of the dasher, presentlydescribed, for the purpose of causing the cream to be agitated orchurned more quicklyl and eiiiciently than if' said ribs were notprovided. y

The number offribs may be varied.

l2 indicates the dasher, the same comprising the central'hub or shaft13, provided at the arms 15. The general shape of the dasher shouldcorrespond to that of the churn-body, within which latter it is adaptedto operate, and therefore in. the present instance it is of conicalshape, and the arms or blades 16 should be so positioned that their pathof movement when the dasher is rotated would be close to the ribs tothus cause the cream to be thrown against the ribs `by the blades.

The means for rotating the dasher comprises a gear-wheel 20, journaledin a bearing secured to one of the uprights 5 and provided with anoperating-crank 21. wheel 2O meshes a smaller gearwheel 22, mounted uponthe outer end of a shaft 23, which is mounted in said upright 5 and abearing-block 24. The inner end of the shaft is provided with abevel-pinion 25, which gears with a bevel-pinion 26, lmounted upon avertical shaft 27 whose upper end has a bearing in the cross-piece 28 ofthe frame and which With the gear' passes down through the cross-piece29 and projects somewhat below the latter. Any other arrangement ofgearing for imparting rotation to the shaft 27 may be employed.

Inasmuch as the churn-body is adapted to be tilted, it is necessary thatthe connection between the shaft 27 and the dasher should be a separableone, and any desired construction which will `permit of the dasher beingdetached from the shaft 27, which imparts rotation to the dasher, may beemployed. vIn the present instance I provide the upper end of thedasher-shaft with a slot 30, within which is litted a plate 31, securedwithin the slot by .pins 32. The plate is adapted to detachably IOOmounted on the shaft 27, which collar when slipped down over the end ofthe plate 3l prevents the latter from working out of the slot 33 in thechurning operation. By slipping the collar upwardly to free the upperend of plate 31 the latter is free to move laterally out of the slot 33when the churn-body is oscillated upon its pivots.

What I claim, and desire to secure by Letters Patent, is-

1. In a churn, the combination with a supporting-frame, of a bodyportion journaled in the frame and adapted to be tilted, a dasherrotatably mounted in the body, said dasher having a central hub or shaftprovided with a slot at its upper end, a vertical shaft mounted in theframe and provided at its lower end with a slot, a plate secured in theslot of the dasher-shaft and adapted to removably engage within the slotof the said vertical shaft, a collar slidingly mounted on the verticalshaft, a lug secured to the churn-body, a bracket secured to an uprightof the frame and having a slot within which the lug is seated, a pinpassing through alined perforations in the ears of the bracket and thelug and means for rotating the last-named shaft.

2. lIn a churn, the combination with a supporting-frame, of a bodyportion journaled in the frame and adapted to be tilted, a dasherrotatably mounted in the body and comprising a central hub or shaft,arms extending through the shaft and arms or blades joining the outerends of the arms, the said central shaft having a Slot at its upper end,a vertical Shaft mounted in the frame and provided at its lower end witha slot, a plate secured in the slot of the dasher-shaft and adapted toremovably engage within the slot of the said vertical shaft, a collarslidingly mounted on the vertical shaft and means for rotating thelast-named shaft.

In testimony whereof I aiix my signature in presence of two witnesses.

WILLIE O. LINDGREN.
